No, because the Linux file I/O APIs are encoding-agnostic, they will
(AFAIK) create the directory with a name that is the exact byte stream
that you type at the mkdir command (or at the Emacs make-directory).

Try doing this in Emacs, and use one of the Latin input methods if the
keyboard doesn't cooperate.

I don't understand this: 2 identical commands one after the other
yield different results?

Really? So there's no way to change the locale to something
non UTF-8?

If that's the case, then we lack ENCODE_FILE (or more generally don't
encode a file name) somewhere.

We could also just install the changes and wait for bug reports, on
the assumption that the problems you see aren't real. Your call.
